iDatalink's Maestro ADS-MRR module, along with the correct interface harness for your vehicle, allows you to install a new car stereo in select late-model Ford, GM, Chrysler, or Volkswagen vehicles while retaining your factory steering wheel audio controls and the use of your factory amplifier, if present.

Here's how it works

First, you connect the Maestro to your Windows-based computer (not compatible with Mac) using the included USB cable, visit www.idatalink.com/maestro, and follow the instructions. Once the unit has been "flashed," it's ready to go. Next, you'll either solder or crimp the vehicle-specific Maestro harness (sold separately) to your new receiver's wiring, just like you would with any Crutchfield wiring harness or wiring adapter.

Important Note: You will also need an additional Maestro vehicle-specific wiring harness that connects your new receiver to the ADS-MRR module and your vehicle's wiring. We will automatically add this harness to your Cart at a discounted price when you purchase a new car stereo and this ADS-MRR module.

Retain steering wheel audio controls, too

The ADS-MRR module also allows you to use your factory steering wheel audio controls with your new receiver. Using the intuitive web programming interface, each factory button can be assigned a specific radio function. Better yet, you can also assign a secondary "press and hold" radio function to each factory button, effectively doubling what can be controlled.

Keeping your factory features with an iDatalink-ready car stereo

If you're buying a compatible Kenwood, Pioneer, or Alpine receiver, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select GM, Ford, Chrysler, or Volkswagen vehicles (see Details for specific functions and installation notes).

Note: Most vehicles will require additional installation parts  please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

General Features

Web-Programmable Radio Replacement Solution: The
iDatalink Maestro RR (ADS-MRR) is part of a web-programmable solution
that allows you to replace the factory radio in many 2006-up
Ford/Lincoln/Mercury, GM, Chrysler/Dodge/Jeep, and Volkswagen vehicles
(requires additional vehicle specific harness). Retained
features will vary by vehicle and aftermarket head unit.

Flashing the Module: The
iDatalink Maestro RR (ADS-MRR) will need to be loaded with correct
firmware before installation. The included USB cable plugs
into your PC and allows you to "flash" the Maestro RR with the
appropriate firmware to prepare it for installation. Just visit iDatalink's
Weblink site, and follow the instructions. System Requirements for
Weblink 6.0 include:

Windows 2000 (SP4), XP (SP2), Vista, and 7

Administrative rights on your PC

Internet Explorer 7.0 or greater (excluding 64-bit version)

Available USB port

Note: iDatalink Maestro RR is not compatible
with a Mac.

Aftermarket Radio Compatibility: The iDatalink
Maestro RR (ADS-MRR) is compatible with a wide variety of aftermarket
radios. Features will vary by vehicle and type of head unit.

Navigation Outputs: The ADS-MRR provides a VSS
(vehicle speed sense), Foot Brake, Parking Brake, and a Reverse Light
output to make installing practically any aftermarket navigation radio
simpler and less time consuming in select Ford/Lincoln/Mercury, GM, Chrysler/Dodge/Jeep, and Volkswagen vehicles.

Steering Wheel Controls: The iDatalink Maestro RR also lets you retain your
Ford/Lincoln/Mercury, GM, Chrysler/Dodge/Jeep, and Volkswagen vehicle's OEM steering
wheel controls when replacing the factory radio with an aftermarket
stereo that offers a SWC input. In addition to retaining the original
steering wheel functions, you can assign secondary press & hold features
to the buttons of your choice. There is only one wire that will have to be spliced when
installing this interface in your compatible Ford/Lincoln/Mercury
vehicle. However, if the vehicle was equipped with factory navigation,
there will be no extra SWC wires to connect in the vehicle. You will not
have to splice any wires to get SWC functionality in a compatible GM, Chrysler/Dodge/Jeep,
or Volkswagen vehicle.

Amp Turn-On Lead: The ADS-MRR provides an amp
turn-on lead to turn on any factory amps when installing virtually any
aftermarket head unit. Both balance & fade control are retained in many
vehicles with analog amplifier systems. 2013-up DNN/DNX-series,
Alpine INE-W957HD/X008/X009, or 2014-up Pioneer AVIC-NEX series head
units also support fading in vehicles with digital amplifier systems.

Note: If you are installing an aftermarket head unit that does not
feature an iDatalink serial port, then you will not be able to fade in vehicles
with digital amplifier systems. In this case, adjust the factory amplifier's
fader prior to installation of the new aftermarket head unit.

Installation Note: Connecting the module, vehicle
specific harness, and aftermarket head unit together
requires hard-wiring numerous wires by soldering or using
Posi-Twist connectors.

Compatibility Note: Click
here for the latest compatible vehicles. Please consult
Crutchfield's
Outfit My Car to see if your specific vehicle is compatible and
what additional accessories will be needed.

Easy Install

Written By BrentL, Hertford, North Carolina on Saturday, February 28, 2015

This product is great along with the additional wire harness and It was recommended by customer service. Once received, I thought oh boy because of all the wires. But after an easy "flash" on my computer, it was pretty much idiot proof after that. The product controls my SWC just as designed on my 2008 F350 with a Jensen V7020 head unit.

Easy hook up

Easy to hook up and use. Wired right into the radio and truck with only a little confusion with the wiring. The Stock AUX did not work with this system and had to be wired into the Radio's second Audio input. The directions were a little vague regarding this and what was required and not required. After a few phone calls it was worked out. Now, AUX is wired as an extra plug and the Audio is connected to my stock AUX. It seems to be a bypass for proper set up. Now I don't have the video in hooked up that goes with the audio in so I don't know if that causes issues if a second video player is hooked up and needs both the vid/audio to play on the unit.

Pros:Easy to use and works great with the stock set up minus the AUX

Cons:System is NOT compatible with MAC for programing. A windows system is a must.
Wiring diagram doesn't explain clearly how the AUX system is set up.

Unit Is A Total FAIL

What I did not like and was VERY disappointing in was the Maestro RR interface. This was supposed to give me all the original functionality of my in car unit, plus all kinds of looks into the gauges and stuff like temp and oil pressure. I also thought it was supposed to simplify the hook up of the car stereo.Don't believe ANY of that!

First off, the instructions DID NOT match the unit I have. Connectors were different (changed) on the unit shipped from what the instructions show. No explanation on how to hook up the new wires.

Second, I still had to solder a LOT of wires. It may have simplified SOMEWHAT the soldering, but there is still a LOT more to do. I thought this was going to be plug and play. It is NOT.

I contacted iDatalink and got NO RESPONSE. Crutchfield responded quickly, but ended up saying for me to get the mic function that is built into my car, I would have to hard wire in a whole new mic...

All in all this unit was a lot of broken promises and expectations...

Pros:None

Cons:It does NOT work as advertised, and makes more promises than it can deliver.

It Works But Not 100%

This setup worked with my existing factory setup but needless to say if I didn't have a friend who is well versed in stereo install I would of been lost. It works though but not until after much troubleshooting with my Pioneer head unit. What frustrates me the most is that after flashing the module with my exact head unit, the module didn't work. Only after a suggestion from Crutchfield to flash the module with a generic Pioneer firmware did the box work. Why allow you to choose your specific unit if it won't work? Strange. Still missing the turn signal sound from my vehicle.

Very Necessary Device

This product is a must for anyone wanting to retain the original vehicle features (such as OnStar, warning chimes, steering wheel controls, etc) with their aftermarket stereo receiver. It is actually pretty easy to install and enables you to print very detailed installation instruction (for your vehicle) from the Maestro website once you complete the required online setup (called flashing). However, don't miss the fine print. This unit can only be setup to work with you specific vehicle, via the use of a PC with internet access. You will need administrative rights to the PC you use for this so you can download the required Active-X file. No Mac computer allowed for this process.

Pros:Works great!
Easy to install with detailed wiring diagrams.

Cons:Can only be setup with a PC! No Mac computer will work for the required online initial setup!

Park Sense and Uconnect not supported 2005 Jeep Grand Cherokee

Written By Andregg, Virginia on Saturday, January 17, 2015

Steering wheel controls are the only retained item for 2005 Grand Cherokee limited. Uconnect isn't a big deal but the parking sensors no longer work when the maestro is in the system. The product is sold with the belief you retain all features that were factory until you install it and then begin the task of troubleshooting only to find that for a given software download and your make/model/year that only some features work.....Painful

Does not retain UConnect on 06 Jeep Grand Cherokee

Written By BobbyH, Houston, TX on Tuesday, January 06, 2015

Firstly, both Crutchfield and iDatalink have been extremely friendly and helpful throughout all my questioning and research. However, it stops there... I've spend at least the past 3-4 days troubleshooting my so called "retained" OEM features just to find out that iDatalink's firmware, well actually the module itself, doesn't support 2006 Jeep Grand Cherokee with UConnect. Granted the steering wheel, amp fader, and other audio features are supported. This still doesn't change the fact you're paying for a feature that doesn't work and sold as if it does. I spoke to a rep at iDatalink, and she apologized about the delay on the front page of their website. Crutchfield may not even be aware of this, but it's definitely something to note if you were indeed looking to keep that stuff going.

Great Interface - Once You Get It Figured Out!

The unit works great, but isn't as simple to hook up as I was thinking. I'm sure it is simpler than another unit I purchased, but not the easiest. The worst thing is, it only works with window. Beware Mac users!

outlook saturn

Opened box read instructions and all went well. No real complaints. Only issue was my reading of MasterSheet and the difference between using factory amp and not using. A quick 5 minute to Crutchfield and my doubts were gone ant proper harness connections were made. So far so good.

Pros:Does what supposed to radio and accessories all work. A novice like me installed it

Cons:A lot of harness to pack in under the head unit on my Saturn outlook.

iDatalink Maestro ADS-MRR Interface Module

Very disappointed in the installation instructions. To flash the module I had to use a friend's windows based computer. I doubt I'm the only person in the world using Apple! Once I searched a forum I figured it out. It works well but not what I've come to expect from a product bought from Crutchfield.

Installed with DNX891HD in 2006 Chrysler 300c

I installed this unit with a Kenwood DNX891HD in a 2006 Chrysler 300c. I couldn't find a lot of information specific to my car, so I figured I would add some notes here:

1. You can go to the iDatalink website and run a simulator for your car that will show you what will work once you program it. This was very helpful.

2. I had to call customer service because the additional harness that is necessary had been wired incorrectly for the ODBII connectors. They were very helpful and knew exactly what the problem was, and they sent me directions on how to re-pin it.

3. This does allow for gauges to show up on the 2006 300c. It also would have allowed me to keep my uconnect. I bypassed the factory amp, and you can turn the factory amp back on from within the Kenwood interface. If you bypass the factory amp, it bypasses the factory speakers, making it unnecessary to cut all of their connections when adding all new amps. You can change many of the other parameters as well.

4. Be careful if you zip tie it inside the car. The reset button protrudes out, and my zip tie got stuck over the button, causing it to continuously reset, which made my system not display.

Pros:Works great!

Cons:They should have provided information about the mis-pinned wires. When I called Crutchfield they knew nothing about it, but when I called iDatalink they knew immediately. You would think they would spread the word to their dealers.
I also wish the reset button was recessed.

Excellent

Very nice product to retain steering wheel controls and Ford Sync for aftermarket HU's. Installed along with a Kenwood DNX691HD and so far i'm happy with the results. Installation was pretty straight forward especially since I used the vehicle specific Ford wiring harness that I purchased separately. Works very well.

09 enclave... Worked for a bit...

It took 3 hours to flash it. It uses windows only!! Tech rep was awesome!! The controls worked but has static when you the steering wheel controls... And after a week, they dont work. The ding still works, but no response from the radio. Simply not worth taking it all apart again to send it back.

Pros:Its plug and play. An awesome tech team for support!

Cons:Windows, windows windows! Instructions are very limited but you can work with them and it seems to have stopped working for no reason!

Must bup for GMC Sierra

This is a must buy for GMC SIERRA. Allowed me to keep everything factory even SiriusXM. These made the installation simple. I didn't have to hunt or look for wires. I'm still able to use the steering wheel controls and was able to program them to however I wanted them. The flashing was simple and quick with their online interface.

Nice Module

Used to retain factory chimes, SW controls, onstar, and backup system features. Easy install into vehicle. Programming was easy with the idatalink site. I had to get use to new chime sounds but no big deal...was like driving a new vehicle.

awesome interface

Navigating the set up was confusing but finally figured it out. Went to the FAQ's on the web site to determine that the internet address provided for actually programming the device options was not correct, and other consumers had the same issue so I guess it was not just me. Overall a great and highly recommended product if you want to use your vehicle's external steering wheel controls. Worth the money no doubt!

Pros:Works well and provides a lot of flexibility for controlling your deck with OEM vehicle controls.

Cons:Instructions were confusing but once navigated the site correctly it worked well and have had no problems!

Pretty cool

Installed in my 09 Silverado with the Kenwood DNX891HD head unit. This unit work as advertised, fairly easy to flash the Maestro to match your vehicle. Just make sure you flash this little unit with the correct parameters. For example if your vehicle does not have any digital displays ie.(speedometer) then don't tell the Maestro you want gauges displayed on your radio, it locked up my radio and resetting did not even work had to disconnect battery to reset radio. Thanks to a call to Crutchfield and some trial and error got system to perform as expected.

Pros:Works everything it supposed and sync'd with vehicle with no problem

Almost Perfect!

This unit integrated my Pioneer 4000nex into my 2006 Dodge Magnum SRT8 almost perfectly. I did loose fade capabilities, because the factory amplifier only accepts inputs from the rear speakers. I also have to switch the rear with the front speaker wires in the harness to be able to hear phone calls. I wish the Maestro could compensate for this. However I was able to retain my advanced EVIC display which I am thrilled about!

Not As Advertised!

Written By SamA, El Paso, TX on Tuesday, August 05, 2014

It took me some time before I purchased this product. Maybe that is why I only rated it 3 stars. Advertised: purchase this product to "retain steering wheel controls and factory amp" This is not accurate at all. I should have listened to some of the lower rated reviews, but you always think some people are just upset. I had this professionally installed by a certified Kenwood Dealer along with a Kenwood 691HD head unit. The steering wheel controls do work but have been altered to do different things other than what the factory settings were. The turn signals and hazards have been altered to some annoying clank and the timing is completely off. So, basically my personal opinion: is that if I knew I would have to listen to the generic fake chimes that this unit is producing, and the controls this activates on the steering wheel, I would have never bought this thing and lost the controls and chimes. Shame on Crutchfield for what I believe is making this unit seem better that what it is and not being forth coming with the information that it is basically a toss up on the interaction at feature when properly installed.

Pros:Your head unit works.

Cons:Not as advertised!

Crutchfield response on Monday, August 18, 2014It's too bad the ADS-MRR didn't work out for you. For other people in this situation, the button assignments can be re-programmed to suit your needs. The installer could've "re-flashed" the device to change those settings for you. There's not much to be done about the sound of the chimes and turn signals, but repositioning the chime speaker might've helped decrease the delay. What's more, since you have an iDatalink compatible Kenwood receiver, in the stereo's Setup menu, you can adjust the door chime volume directly. This also might help alleviate the delay.

Must have!

If you have any kind of factory hands free/steering wheel controls, you absolutely MUST get one of these. The ease of integration and programming, plus the added features and of course retaining the factory controls and SYNC in my case, is invaluable.

Pros:Easy to install and use! Excellent customer support from the MFG!

iDatalink Maestro ADS-MRR

This adapter works great and the customer support is awesome. I installed this in a 2006 Ram and still having problems with it not tuning my factory amp on every time. But, this thing will integrate your factory bells and whistles very nicely. It is highly customizable and seems to be very stable even in the N. Ca summer heat.

Pros:Easy to set up
Customizable

Cons:Have to remove to re-flash
Have to have a windows machine to flash

Nice, but not as advertised

Written By Daniel, Mobile, AL on Wednesday, July 16, 2014

The device has numerous options with the programmable interface, but does not have any additional features over the competition in my 2013 Jeep Wrangler. Several desirable features do not work from the device despite complete, correct connections as per the instructions and correct harness (sold seperate)

Pros:Easily customizable buttons

Cons:Does not correctly translate illumination wire, radio stays fully bright all the time
Does not detect reverse, had to go around the device to the reverse light switch.
Does not translate speed pulse, making problems with A/V and GPS Navigation.
Does not pass Track or GPS information back to the Chrysler Uconnect EVIC display, an OEM function.

Crutchfield response on Tuesday, July 22, 2014Unfortunately, the last issue mentioned (sending track or GPS information back to the Uconnect display) can't be fixed. According to our Techs, that's not something that can be done once you install almost any aftermarket stereo. Our Tech Support team has reached out to the customer to see they can help solve some of the other problems. Remember, lifetime Tech Support comes free with any Crutchfield purchase.

Maestro

I installed this on a 2011 Silverado and everything worked except the Truck Bluetooth. I'm very happy with this purchase. I did not have to cut any wires on my truck.

Pros:Didn't have to splice any wires on my truck.
Programming the unit for my truck was very easy......

Cons:Factory Bluetooth didn't work and I didn't like the factory sirius interface with the Kenwood. The station or title didn't show up on the screen. The only information was the channel number. I installed an aftermarket satellite tuner and it worked much better.

Just like factory

The idatalink Maestro worked as advertised. I had to do a little soldering and what not but no problems. Installed it and it worked. The only thing that was an inconvenience was the lack of Apple support. But luckily the neighbor came through and let me use his (PC) laptop to do the programming. Other than that, I had no problems and would recommend this product.

Pros:Simple to program. Adapter is fairly small and easy to tuck out of the way.

Cons:Must have a PC to program. And a little labor intensive, not a plug and play device.

Lots of functions for such a little box

Great product for plug and play and allows my to view a lot of the gauges for my Silverado and see ce codes when thrown. The current model that I have does have a few annoying factors with one of the ways it gets hooked up. Whenever the blinker clicks it cuts out the front left speaker which is annoying. I found out how to turn off the alarm but other alarms from car like low gas or seatbelt also cuts off the speaker.

Pros:Can see lots of gauges from truck, very programmable.

Cons:Sound cut off is very annoying however this model is now discontinued so the replacement may have fixed that.

Neat but not ready for prime time

I bought this to integrate a Kenwood DNX691DX into my 2010 GMC Sierra XFE and while it did integrate most of the functions, missing were some of the chimes (door open for example) and reasonable integration for the OEM XM receiver. If you select the XM receiver from the main menu then you will get a message to check the receiver. You have to go to the first sub menu, select "My Sierra", then XM radio from that screen to get the XM radio to work. Very distracting while driving!! Another quirk is the chimes that do work... If you adjust the chime volume so it doesn't blast you out of the car then you cannot hear the turn signal reminder.

Pros:Makes connecting a radio to your car/truck somewhat easy and it will pass some of the vehicle's data to the radio.

Cons:Finding documentation and connection (maestro - radio - vehicle) data is difficult. iDataLink's WEB site isn't easy to navigate but with patience you will eventually find the info you need to install their device.

Nissan Integration iDatalink Maestro ADS-MRR

This is a great product. I was able to integrate the Maestro Rr with my new Kenwood DNX891 head unit and keep my Steering controls. I am able to view gages and ODBII Engine diagnostics on the Kenwood until. I was able to easily link the Kenwood until the factory Bose amplifiers / Speakers

Pros:Easy instructions for connections based on vehicle type. The firmware flashing process for vehicle was easy to follow.
Nice having the ability to view vehicle info on my head until Read/Reset Check Engine Codes. I can view dash gauges. My steering wheels controls work great and can be reprogramed to accommodate different functionality.

Cons:I had to call Crutchfield connection points for reverse and parking brake as they were not provided in the harness. The Crutch filed web site said the Maestro Rr was not compatible with my 2011 Nissan Maxima even though it's fully supported by ADS Idatalink.

5 DAY INSTALL

Written By CHRISTIAN, CA on Tuesday, May 27, 2014

I'm on day 5 and the unit still does not work. I installed the Maestro RR with the suggested GM harness, a Pioneer AVIC-6000NEX, in a 2007 Chevy Avalanche. After the initial install, the steering wheel controls worked, but I could not get my dash lights to turn off, even when the vehicle was off. The speaker output was almost nonexistent and the amp turn on was blowing fuses. After several hours of going over the wiring, and in fear of blowing up my amp and head unit, I put the install on hold. I called IDATA in the morning and the tech told me that the pink and white wire was seated incorrectly on their harness. I removed the wire and put it into the correct pin placement. The tech also told me to remove the "blockers "(an inline series of caps) from the speaker wire. These steps seemed to do the trick. However, after about 5 minutes the volume began to increase and decrease all on its own. I had to turn the volume down manually. Then the steering wheel controls ceased to work at all. I called tech support again and they told me that I needed to solder a 47 ohm resister on the red wire of the control plug. I performed that task. The volume still has a mind of its own and the steering wheel controls do not respond. I'm not certain what they will suggest next. I'm incredibly frustrated. IDATA seems to desire to place blame on Pioneer. I have three letters for you, if you are planning a Pioneer head unit install with the Maestro, PAC.

Crutchfield response on Wednesday, June 04, 2014The customer decided to return the ADS-MRR after going way above and beyond in troubleshooting the situation. Normally, the MRR does not require this kind of headache. We're reviewing this application and will document things accordingly so the next Avalanche owner knows what to expect.

Good Product

Great product. Installation was a pain but keep your cool and you'll get through it. Glad I got it from Crutchfield, because they have awesome tech support. The product does exactly what it says. Make sure you buy the maestro wiring harness for your vehicle (sold separately).

Is this the best you can do?

Seems to work great. Here's my problem. I'm an enlightened Mac user. It's all I use. I pay extra because their products work. I have a several years old iMac. Works like a boss. I have three iBooks. Awesome. iPods, iPhones... All of my friends are enlightened Mac users. I get this thing in the mail and it not only requires a PC to flash software for my application, IT REQUIRES INTERNET EXPLORER! Ok, maybe you use PC's, you're forgiven. Do you honestly have the latest version of internet Explorer? You will, if you buy this product. I was not happy when I had to start calling people asking if anyone would mind me using their PC's so that I could install my new sound system.

Pros:It works fine.

Cons:It only works with PC and Windows Explorer 7 or higher. Plus you have to install a third party software to flash the thing.

iDatalink Maestro ADS-MRR

It worked after I called and got another one sent. Flashing the module on my 08 GMC required me to turn off turn signal click in order for it to not shut off all the speakers on the left side of my truck when the turn signal was on. If you have a GM and use this good luck.

Works

Seems to work well. Downloading the new file on it was simple and easy. As far as wiring goes it's definitely recommend that you buy the wiring harness for this you because it's a sea of wires if you dont.

Naestro works perfectly

I'm usually hesitant to give a 5 star rating but this device worked perfectly and was easy to install. I have a 2012 Jeep Wrangler and everything worked flawlessly.

Pros:Easily adapts to your vehicle by connecting it to your computer and then going to the iDatalink website, selecting your vehicle, steering wheel type and stereo. Just click the flash button and your Maestro is programmed.

Cons:The iDatalink website programming function only works with PC's, not Macs.

Needed to call Crutchfield for it to work properly.

Installed on a 09 Challenger with Pioneer AppRadio 3. I picked this unit over the PAC because I was told It would work with Uconnect. It doesn't. Still a good quality unit that was able to keep steering wheel controls. I like that you program it on the web and can change the funtions of the steering wheel controls to your liking.

If you have my setup, you will need a modified steering wheel control cable that Crutchfield can provide. Only thing is you have to call customer support. They were great, but I wish they would have told me this before I spent time troubleshooting thinking it was something wrong on my installation.

Pros:Programable steering wheel controls that can be changed to the users liking via the website.

Cons:Uconnect will not work (although I was told it would) with late model Challenger/Mopar and AppRadio 3. Needed modified steering wheel control cable (for my setup) that should have been included with original purchase.

Flawless operation

I wanted to retain Sync and SWC's in my 2013 Mustang and this looked like a good option. The installation is a breeze with the optional manufacturer specific harness. Soldering the stereo harness in took longer than anything else, but was no problem. Flashing the module is easy to do and allows you to assign two functions to each button which is nice.

Sync Integration is awesome!

If it wasn't for this unit, I wouldn't have an aftermarket head unit in my F150! The unit is very easy to set up and install using the T-harness sold for Fords. Only about 10 connection to make to the head unit and everything else is plug and play. Programming is a snap (but you must use Internet Explorer.) In use it just works. About the only thing bad I can say is that there's a bit of a delay when pressing the voice button. An ADS rep offered that since I'm just using it for phone, press and hold the voice button for fast access to the phone menus.

Easy-ish. Nothing is as easy as it seems

Upon reviewing procedures for installing my stereo, I was pretty optimistic regarding the ease at which this would install. Dash came apart easily and almost everything plugged in. For my chrysler product, the adapter had an extra harness but, must be extra... or so I thought at first. Secondly, I had to go in and solder up all the wires (it sounds plug and play when you order it, but plugging to an aftermarket stereo, have to solder the stereo harness to the Idatalink pigtail. Now I'm ready to go. Everything should be plug and play at this point. WRONG. Turns out, the software in the iDatalink actually controls the routing of the audio, so, bad program equals no sound. Of course, I programmed it and it said it took, so I thought I was missing a connection or did something wrong. It was a saturday, so no customer support available, so I kept plugging away, checking every little thing. Turns out, programming didn't go right. After struggling to get the thing flashed, it worked. I don't know what happened the first 39 times, but the 40th time with the same settings, I plugged it in and boom... audio. My fader is still all messed up. Fade to the back and it goes away. But all the speakers and subwoofer are working. When watching a movie, the quadraphonic sound fades the proper direction when a helicopter flies overhead on screen, but I can't fade it to test each speaker. Other than programming on a bad website, it was worth it to get the functionality.

Pros:Easy plug and play once you get the website to work properly.

Cons:Not so easy to get and more so CONFIRM that it's actually programmed right. An issue when you have an untested stereo. Which is broken?
Soldering or butt connecting required. You might expect that to be the case, but I figured, I told them what stereo and what car... they would give me a harness. Naive maybe, but I don't install new stereos for a living.
If it will run with a USB cord, possible to leave a USB connected run to the glove box to change settings without disassembling.

iDatalink Maestro ADS-MRR Factory Integration Adapter

The maestro was easy to program and install. You don't need to be a electrical engineer to follow the diagram and hook it up. The feature I wanted was an interface with the SYNC system in my Ford F150. This device hits it out of the park.
